5G Core Network Functions

5G core network has a service-based architecture. Network functions provide services via standard APIs and the HTTP 2.0 protocol. 5G Software offerings include

• Access and Mobility Management Function (AMF)
  • supports termination of NAS signaling, NAS ciphering & integrity protection, registration management, connection management, mobility management, access authentication and authorization, security context management
• Authentication Server/Function (AUSF)
  • acts as an authentication server
• Network Slice Selection Function (NSSF)
  • supports selecting of the Network Slice instances to serve the UE, determining the allowed NSSAI, determining the AMF set to be used to serve the UE.
• Unified Data Management (UDM)
  • supports generation of Authentication and Key Agreement (AKA) credentials, user identification handling, access authorization, subscription management.
• Unified Data Repository (UDR)
  • stores user subscription data, policy data, structured data for exposure, and application-level meta data such as Packet Flow Descriptions (PFDs). It provides the necessary interfaces for storing and retrieving of data in the repository.
• Session Management Function (SMF)
  • Supports session management (session establishment, modification, release), UE IP address allocation & management, DHCP functions, termination of NAS signaling related to session management, DL data notification, traffic steering configuration for UPF for proper traffic routing.
• Policy Control Function (PCF)
  • supports unified policy framework, providing policy rules to CP functions, access subscription information for policy decisions in UDR.
• Network Repository Function (NRF)
  • Supports service discovery function, maintains NF profile and available NF instances.
• User Plane Function(UPF)
  • supports packet routing & forwarding, packet inspection, QoS handling, acts as external PDU session point of interconnect to Data Network (DN), and is an anchor point for intra- & inter-RAT mobility

5G Software Core offers

• A Disaggregated architecture that includes cloud concepts such as microservices
• Open-core architecture that uses open APIs to securely expose information and capabilities
• Flexible deployment options both physical and virtual, including a range of network function virtualization infrastructures (NFVIs)
• DevOps to quickly and continuously deliver new features and software improvements
• A common data layer stores all functional state information
• AI driven integrated real time analytics to measure core network performance and to dynamically adjust network resources in real time to changes in service demands
